Control system switchover completed in three hours

The Husky Energy ethanol plant at Lloydminster, Saskatchewan commenced operations in September 2006.
A further ethanol plant at Minnedosa, Manitoba is scheduled to start up in late 2007.
The plants are the largest of their kind in western Canada.
Each of the two new plants will produce 130 million litres (34.3 million gallons) of ethanol annually, to be blended up to 10 percent into gasoline products to help motorists reduce greenhouse gas emissions.
The grain-based processes will use high-starch feed-quality wheat as feedstock, consuming approximately 350,000 tonnes annually for each plant.
The Foxboro DCS implementations each communicate with approximately 1,800 direct I/O points and 2000 I/O points through multiple PLCs.
The networked control systems at the plant each include three pairs of Foxboro ZCP 270 control processors in fault-tolerant configurations connected with distributed I/O cabinets at nine process units throughout each plant.
The systems perform a wide variety of control functions, including batch processing applications.
At the Lloydminster site, the ethanol plant controls are integrated with existing I/A Series control consoles at the adjacent existing Husky Lloydminster heavy oil upgrader facility, which has been under I/A Series control since 1992.
Invensys Canada is also providing various professional services for each DCS implementation, including database engineering, graphics development, configuration services, start-up assistance and training for engineers and operators.
